Price Comparison
The be quiet! Pure Power 13 M 850W Power Supply is significantly more expensive than the MSI MAG A750BN PCIE5, priced at C$173.21 compared to C$84.64. This difference of C$88.57 reflects the varying features and capabilities of both power supplies. While the MSI model offers basic functionality at a lower price, the be quiet! model aims for high efficiency and performance, making it a more premium choice. Buyers should consider whether the additional investment in the be quiet! model aligns with their specific needs for power supply performance and reliability.
Efficiency Ratings
In terms of efficiency, the be quiet! Pure Power 13 M boasts an 80 PLUS Gold certification, indicating it can achieve up to 94.4% efficiency under load. This high rating translates to lower power consumption and operating costs, which can be a crucial factor for users looking to build energy-efficient systems. On the other hand, the MSI MAG A750BN is certified as 80 PLUS Bronze. While this certification still signifies respectable efficiency, it falls short compared to its Gold-rated counterpart, making the be quiet! power supply a better option for those prioritizing energy efficiency and long-term savings.
Power Output
When it comes to power output, the be quiet! Pure Power 13 M delivers a robust 850W, ensuring it can handle even the most demanding systems with ease. This power supply features a single massive 12V rail capable of supporting high transient loads, making it suitable for next-gen processors and graphics cards. Conversely, the MSI MAG A750BN does not specify its total wattage in the provided data. However, given its lower price point and Bronze certification, it is likely designed for less demanding setups. Users with high-performance needs will benefit significantly from the 850W capacity of the be quiet! model.
Cooling Technology
Cooling capabilities differ notably between the two products. The be quiet! Pure Power 13 M features semi-passive Zero-RPM cooling, allowing the fan to turn off completely under low loads, promoting a quieter operation. This design is particularly appealing for users who want a silent computing experience. In contrast, the MSI MAG A750BN does not mention any advanced cooling technology or features, which may result in a noisier operation under load. For those who value a silent system, the be quiet! model stands out as the clear choice.
Build Quality and Warranty
The be quiet! Pure Power 13 M is crafted to provide high-class stability and reliability, underscored by its LLC topology, which ensures excellent voltage regulation. While the product details for the MSI MAG A750BN do not elaborate on its internal construction, it does come with a 5-year limited warranty, promising long-term reliable operation. However, the perceived build quality of the be quiet! model, given its higher price and advanced features, may appeal more to enthusiasts and gamers who require robust performance.
Compatibility with Future Technologies
Future-proofing is a key consideration for many buyers, and the be quiet! Pure Power 13 M excels in this area. It adheres to ATX 3.1 specifications and includes native support for the 12V-2x6 connector, necessary for next-generation PCIe 5.1 graphics cards. This feature makes it an ideal choice for users planning to upgrade their systems with the latest technology. The MSI MAG A750BN, while compatible with PCIe 5, does not offer the same level of future readiness as its higher-end counterpart. For consumers looking to invest in a power supply that will remain relevant for years, the be quiet! model is the superior option.
User Experience and Noise Levels
User experience is significantly influenced by the noise levels produced by a power supply. The be quiet! Pure Power 13 M is designed to operate quietly, thanks to its Zero-RPM cooling feature and airflow-optimized fan blades. This makes it particularly appealing for users who prioritize a noise-free environment, such as those working in offices or gaming setups. The MSI MAG A750BN, lacking specific noise-reduction features, may not offer the same level of quiet operation. Users sensitive to noise may find the be quiet! model more suitable for their needs.
Which should you buy?
Choosing between the be quiet! Pure Power 13 M 850W Power Supply and the MSI MAG A750BN PCIE5 ultimately depends on your specific requirements and budget. If you seek a high-performance, efficient, and quiet power supply that can support demanding systems and future upgrades, the be quiet! model is well worth the investment at C$173.21. However, if you are on a tighter budget and need a basic power supply for less demanding applications, the MSI MAG A750BN at C$84.64 provides solid functionality, albeit with limitations in efficiency and power output.
